Description

Technical Field

[0001] The present invention relates to a safety lamp mounting support device, and more particularly to a structural technique for mounting and supporting a safety lamp used in various night works such as night construction on roads to a partition frame that partitions a construction area or the like.

Background Art

[0002] A safety lamp is an essential lighting fixture installed to enhance the visibility of a construction area or the like and ensure the safety of pedestrians, passing vehicles, etc. in various night works. For example, it is used by being mounted on a partition frame that partitions a construction area at a road construction site or the like.

[0003] For this purpose, various mounting support devices for attaching and supporting a safety lamp to a pipe constituting the partition frame have been developed (see, for example, Patent Document 1, etc.).

Summary of the Invention

Problems to be Solved by the Invention

[0007] However, with the structure of the conventional mounting support device described above, both the mounting and fixing of the mounting part to the partition frame and the insertion and fixing of the body of the safety lamp to the insertion support part are done by tightening and fixing screws. As a result, the installation and removal of the safety lamp requires a lot of effort and time, resulting in very poor work efficiency.

[0008] In other words, since the partition frames mentioned above at road construction sites are installed throughout the entire construction site, the installation area of ​​these partition frames is usually wide, corresponding to the size of the construction site, and therefore the number of safety lights attached to the partition frames is generally very large.

[0009] Furthermore, given the structure of conventional mounting support devices, which require considerable effort and time to install and remove each safety light as described above, the installation of all safety lights on the partition frame would require an enormous amount of effort and time.

[0010] In this regard, the use of power tools is essential for tightening and loosening fastening screws. However, even in this case, the tightening and loosening process requires inserting safety lights and switching to power tools, resulting in a complex workflow. Furthermore, the size of the fastening screws may vary, requiring the replacement of the screw-operating tip of the power tool, which increases the labor and time required for the work.

[0011] Furthermore, the loss of the tightening screws, which are components of the mounting support device, is actually quite common at work sites, indicating that there is room for further improvement in this respect as well.

[0012] The present invention has been made in view of the aforementioned conventional problems, and its purpose is to provide a safety light mounting support device that can reduce and shorten the labor and time required for installing safety lights on partition frames at work sites such as road construction sites. [Means for solving the problem]

[0013] To achieve the above objective, the present invention provides a safety lamp mounting support device for mounting and supporting a safety lamp, which has a cylindrical body and a main body having a diameter larger than the body, to a partition frame, comprising: a mounting and fixing part for mounting and fixing to the partition frame; and a safety lamp support part that protrudes from the mounting and fixing part and has a cylindrical holding part having an insertion-side opening at one end into which the body of the safety lamp can be inserted, wherein the cylindrical holding part is formed continuously from the insertion-side opening and has a cylindrical inner surface corresponding to the cylindrical outer surface of the body of the safety lamp, an insertion recess on the cylindrical inner surface that allows the convex part of the body of the safety lamp to be inserted in the axial direction, a rotation space on the other side of the axial direction from the insertion recess that allows the convex part to rotate in the circumferential direction, and a positioning recess on the other side of the axial direction from the rotation space into which the convex part is fitted and whose rotation in the circumferential direction is restricted, wherein the insertion recess and the positioning recess are arranged at positions separated from each other in the circumferential direction.

[0014] A preferred embodiment employs the following configuration. (1) The safety lamp support portion comprises a plurality of cylindrical holding portions, and these plurality of cylindrical holding portions are integrally formed such that the axes of the inner circumferential surfaces of the cylinders of each cylindrical holding portion are perpendicular to each other, and the intersection of these inner circumferential surfaces of the cylinders forms the rotation space.

[0015] (2) The partition frame is a rod-shaped body, and the mounting and fixing portion comprises a fitting portion that is removably fitted and locked to the outer circumference of the partition frame, and a fastening and fixing member that fastens and fixes the fitting portion to the outer circumference of the partition frame in a manner that can be fastened and released.

[0016] (3) The partition frame is a rod-shaped body, and the fastening fixing member of the mounting fixing part is in the form of a fastening spring member made of metal wire, the base end of which is pivotably supported in the fitting part, and the tip end of which is locked to the fitting part in a manner that it can be locked and unlocked, and when the fitting part of the mounting fixing part is fitted and locked to the outer circumference of the partition frame, the spring member swings and its tip is locked to the fitting part, so that the fitting part and the spring member elastically clamp and fix the outer circumference of the partition frame from both sides, and the mounting fixing part is attached and fixed to the partition frame.

[0017] The structure of the partition frame for attaching the mounting and fixing part of the safety light according to the present invention is not particularly specified, but a cylindrical pipe is preferably used. In addition, a type of cylindrical pipe commonly used is called a single-pipe pipe. [Effects of the Invention]

[0018] The present invention provides a safety light mounting support device that can reduce the labor and time required for installing safety lights at work sites such as road construction sites.

[0019] (1) By arranging the insertion recess and positioning recess formed in the cylindrical holding portion provided on the safety lamp support portion at positions separated from each other in the circumferential direction, an anti-detachment structure can be constructed that prevents the safety lamp supported on the safety lamp support portion from being accidentally pulled out in the axial direction by the protrusion provided on the body portion engaging with the cylindrical inner surface of the cylindrical holding portion. Therefore, the safety light support does not require conventional tightening screws, and the safety light can be supported simply by aligning the protruding part of the safety light with the positioning recess and placing it on top. As a result, the installation and removal of the safety light does not require much effort or time, and the work efficiency is very good.

[0020] Therefore, even if a very large number of safety lights are to be installed on partition frames at road construction sites, the labor and time required for installation are significantly reduced compared to conventional methods, as there is no need to use power tools.

[0021] (2) Furthermore, the safety light mounting support device of the present invention does not include any fastening screws or other components that can be separated from the device, so there is absolutely no risk of losing these fastening screws or other components at conventional construction sites.

[Modes for carrying out the invention]

[0023] Embodiments of the present invention will be described in detail below with reference to the drawings. Note that the same reference numerals throughout the drawings indicate the same component or element.

[0024] Embodiment 1 Figures 1 to 13 show the safety light mounting support device according to the present invention. Specifically, this safety light support device 1 is for mounting and supporting the safety light 50 shown in Figure 11 on a pipe 51 which is a partition frame. The pipe 51 is a cylindrical member that constitutes a frame that forms a partition indicating the boundary of a restricted area such as a construction site. In this embodiment, the pipe 51 is represented in drawings as a so-called single pipe. The mounting and fixing part 2, which is attached and fixed to the pipe 51, and the safety light support part 3, which positions and supports the safety light 50, are integrally formed.

[0025] In other words, although not specifically shown in the illustration, the safety light 50 is used in various nighttime construction work. For example, it is a lighting fixture that is attached to the pipe 51 of the partition frame that divides the construction area at road construction sites, etc.

[0026] As shown in Figure 11, the above-mentioned safety light 50 consists of a main body 52 in which a light-emitting part such as an LED is provided inside a transparent container, and a cylindrical body 53 integrally provided at the lower end of the main body 52 and containing a power supply unit such as a rechargeable battery. The main body 52 is configured to be radially larger than the body 53. Power supplied from the power supply unit causes the light-emitting part of the main body 52 to emit light, which then passes through the transparent container of the main body 52 and emits light to the outside.

[0027] The mounting and fixing part 2 is attached and fixed to the pipe 51 and comprises a fitting part 4 and a tightening and fixing member 5.

[0028] The fitting portion 4 described above is removably fitted and locked onto the cylindrical outer circumference of the pipe 51, and is a single molded plastic product formed integrally with the safety light support portion 3.

[0029] The fitting portion 4 in the illustrated embodiment consists of a cylindrical body having a cylindrical inner surface 4a corresponding to the cylindrical outer surface 51a of the pipe 51, and is in the form of an arc-shaped member in which a part of its circumferential direction is cut out to form an opening 4b.

[0030] The fitting portion 4 is configured to be inserted through the opening 4b of the fitting portion 4 onto the cylindrical outer circumference of the pipe 51 and then elastically fitted and locked into place.

[0031] The above-mentioned fastening and fixing member 5 fastens and fixes the fitting portion 4 to the cylindrical outer circumference of the pipe 51 in a way that allows for fastening and release, and is in the form of a fastening spring member made of metal wire.

[0032] The specific structure of the fastening and fixing member 5 is in the form of a fastening spring, which is made by bending a metal wire to form an arc-shaped rectangular frame. Its base end 5a is pivotably supported near one end of the opening 4b of the fitting portion 4, and its tip 5b is locked and unlocked near the other end of the opening 4b of the fitting portion 4.

[0033] Then, with the fitting portion 4 of the mounting and fixing portion 2 fitted and locked to the cylindrical outer circumference of the pipe 51, the tightening and fixing member 5 is swung to lock its tip portion 5b to the fitting portion 4, so that the fitting portion 4 and the tightening and fixing member 5 elastically clamp and fix the cylindrical outer circumference of the pipe 51 from both sides, thereby attaching and fixing the mounting and fixing portion 2 to the pipe 51.

[0034] The safety light support section 3 is for positioning and supporting the safety light 50, and comprises three cylindrical holding sections 6A, 6B, and 6C.

[0035] These three cylindrical holding parts 6A, 6B, and 6C each have a structure for inserting and holding the body 53 of the safety lamp 50, and are configured so that one of the cylindrical holding parts 6A, 6B, or 6C is selected and used so that the safety lamp 50 is supported in a vertical position, corresponding to the arrangement of the pipe 51 to be mounted and supported.

[0036] For this purpose, the three cylindrical holding portions 6A, 6B, and 6C are integrally formed such that their respective axes XA, XB, and XC are perpendicular to each other at their longitudinal central portions.

[0037] The structures of the cylindrical holding parts 6A, 6B, and 6C described above are all basically the same, and the structure of the first cylindrical holding part 6A will be described below.

[0038] The first cylindrical holding portion 6A is equipped with a circumferential positioning structure for the body portion 53 of the safety lamp 50 and a structure to prevent the body portion 53 from being pulled out.

[0039] The first cylindrical holding portion 6A is in the form of a cylindrical member having a cylindrical inner surface 6a that corresponds to the cylindrical outer surface 53a of the body portion 53 of the safety lamp 50.

[0040] In the illustrated embodiment, the inner diameter of the cylindrical inner surface 6a is set to be slightly larger than the outer diameter of the body portion 53, and its length is set to correspond to the length of the body portion 53.

[0041] Specifically, in the cylindrical inner circumferential surface 6a of the illustrated embodiment, as will be described later, the length dimension of the cylindrical inner circumferential surface 6a is set such that, with the lower end surface 52a of the main body portion 52 of the safety lamp 50 in contact with and locked to the upper end surface 6b formed on one end side of the first cylindrical holding portion 6A, the protrusion 54 of the body portion 53 of the safety lamp 50 protrudes into and locks into the positioning recess 7b of the first cylindrical holding portion 6A.

[0042] Furthermore, the inner circumferential surface 6a of the first cylindrical holding portion 6A is provided with a continuous insertion recess 7a that allows the projection 54 provided at the lower end of the body portion 53 to be inserted in the direction of axis XA from an insertion-side opening formed at one end of the first cylindrical holding portion 6A, a rotation space 8 that allows the projection 54 to rotate in the circumferential direction, and a positioning recess 7b that positions and locks the projection 54 in the circumferential direction. The insertion recess 7a and the positioning recess 7b are arranged to be separated by a predetermined angle (90° in the illustrated embodiment) in the circumferential direction of the inner circumferential surface 6a of the cylinder.

[0043] Furthermore, in this embodiment, the rotation space 8 is formed by the intersection of the orthogonal points of the cylindrical inner circumferential surfaces 6a, 6a, 6a of the three cylindrical holding parts 6A, 6B, and 6C.

[0044] Furthermore, the body portion 53 of the safety lamp 50 can be inserted in the direction of axis XA by inserting its protrusion 54 into the insertion recess 7a of the first cylindrical holding portion 6A, and rotation in the circumferential direction is permitted when the protrusion 54 is in the rotation space 8. In addition, rotation in the circumferential direction is restricted when the protrusion 54 engages with and locks into the positioning recess 7b, so that the positioning recess 7b forms a circumferential positioning structure and the safety lamp 50 is positioned in the circumferential direction.

[0045] In other words, the cooperation (locking structure) between the protrusion 54 of the body 53 of the safety lamp 50 and the positioning recess 7b of the first cylindrical holding part 6A forms a circumferential positioning structure for the body 53 of the safety lamp 50, and the cooperation (locking structure) between the protrusion 54 and the boundary portion between the rotation space 8 of the first cylindrical holding part 6A and the inner circumferential surface 6a of the cylinder forms a structure to prevent the body 53 of the safety lamp 50 from being pulled out.

[0046] As mentioned above, the basic structures of the second cylindrical holding portion 6B and the third cylindrical holding portion 6C are the same as the basic structure of the first cylindrical holding portion 6A described above. Therefore, the structures of the cylindrical inner surface 6a, insertion recess 7a, rotation space 8, and positioning recess 7b in the second and third cylindrical holding portions 6B and 6C are basically the same as the structures of the cylindrical inner surface 6a, insertion recess 7a, rotation space 8, and positioning recess 7b in the first cylindrical holding portion 6A described above.

[0047] However, in order to mount and support the safety light 50 in a vertical upright position on the upper side of the horizontally arranged pipe 51, as shown in Figure 1, using the safety light mounting support device 1 configured as described above, the first cylindrical holding part 6A of the three cylindrical holding parts 6A, 6B, and 6C of the safety light support part 3 is used.

[0048] First, attach the safety light mounting support device 1 to the pipe 51.

[0049] In other words, as described above, the mounting and fixing part 2 of the safety light mounting support device 1 is attached and fixed to the cylindrical outer circumference of the horizontally positioned pipe 51. First, the tightening and fixing member 5 of the mounting and fixing part 2 is swung open relative to the fitting part 4, and the fitting part 4 is inserted through its opening 4b onto the cylindrical outer circumference of the pipe 51 and elastically fitted and locked in place.

[0050] At this time, the first cylindrical holding portion 6A of the safety light support portion 3 is made vertical, and in this state, the tightening and fixing member 5 is swung in a closing direction relative to the fitting portion 4, and its tip portion 5b is locked and fixed to the fitting portion 4, so that the fitting portion 4 and the tightening and fixing member 5 elastically clamp and fix the cylindrical outer circumference of the pipe 51 from both sides, thereby attaching and fixing the mounting and fixing portion 2 to the pipe 51. As a result, the safety light mounting support device 1 is attached and fixed to the pipe 51.

[0051] Next, the safety light 50 is attached to the first cylindrical holding part 6A of the safety light mounting support device 1, which is in a vertically upright position.

[0052] Specifically, referring to Figures 12 and 13(a), the body 53 of the safety lamp 50 is positioned relative to the cylindrical inner circumferential surface 6a of the first cylindrical holding part 6A, with the protrusion 54 positioned so that it can be inserted into the insertion recess 7a from the insertion opening formed at one end of the first cylindrical holding part 6A (see Figure 12(b)), and inserted from above, thereby positioning the protrusion 54 in the rotation space 8 (Figure 13(b)). Then, in this state, the body portion 52 is rotated in the circumferential direction to align the protrusion 54 so that it can enter and lock into the positioning recess 7b, and the safety light 50 is then dropped down by its own weight, so that the lower end surface 52a of the main body portion 52 comes into contact with and locks into the upper end surface 6b formed on one end of the first cylindrical holding portion 6A, and the protrusion 54 enters and locks into the positioning recess 7b, restricting rotation in the circumferential direction and positioning the safety light 50 in the circumferential direction (Figure 13(c)).

[0053] As a result, the safety light 50 is mounted and supported in a vertical upright position facing a predetermined direction relative to the safety light support portion 3, that is, the pipe 51. Furthermore, the mounted and supported safety light 50 does not need to be tightened and fixed by the safety light support portion 3; it is sufficient that the lower end surface 52a of the main body portion 52 abuts and locks against the upper end surface 6b of the first cylindrical holding portion 6A.

[0054] Furthermore, in the mounted and supported state of the safety light 50, the positioning recess 7b is positioned to protrude radially outward from the first cylindrical holding portion 6A beyond the portion of the cylindrical inner circumferential surface 6a corresponding to the axial direction. Therefore, the cooperative action of the protrusion 54 of the body portion 53 and the rotation space 8 of the first cylindrical holding portion 6A effectively prevents the body portion 53 of the safety light 50 from accidentally coming loose or being intentionally pulled out by illegal acts.

[0055] As described in detail above, the safety light mounting support device 1 of this embodiment provides the following unique advantages.

[0056] (a) The safety lamp mounting support device 1 is integrally formed with a mounting and fixing part 2 that is attached and fixed to the pipe 51 and a safety lamp support part 3 that positions and supports the safety lamp 50. The mounting and fixing part 2 includes a fitting part 4 that is removably fitted and locked to the cylindrical outer circumference of the pipe 51 and a tightening and fixing member 5 that tightens and releases the fitting part 4 to the cylindrical outer circumference of the pipe 51. The safety lamp support part 3 includes three cylindrical holding parts 6A, 6B, and 6C that insert and hold the body 53 of the safety lamp 50. Furthermore, since these cylindrical holding parts 6A, 6B, and 6C are equipped with a circumferential positioning structure for the body part 53 and a structure to prevent the body part 53 from being pulled out, the attachment and fixing of the mounting fixing part 2 to the pipe 51 and the positioning and support of the safety light 50 to the safety light support part 3 can both be performed with simple operations without requiring conventional tightening screws. As a result, the installation and removal of the safety light 50 does not require much effort or time, and the work efficiency is very good.

[0057] Therefore, even if a very large number of safety lights 50 are installed on partition frames at road construction sites, the labor and time required for installation are significantly reduced compared to conventional methods, as there is no need to use power tools.

[0058] (b) Furthermore, the safety light mounting support device 1 of this embodiment does not include any fastening screws or other components that can be separated from the device, so there is no risk of losing these fastening screws or other components at construction sites or other locations, as in the conventional method.

[0059] Embodiment 2 This embodiment, shown in Figures 14 and 15, is a modification of the method of use of the safety light mounting support device 1 in Embodiment 1.

[0060] In other words, in this embodiment, as shown in Figure 14, the safety light 50 is vertically mounted and supported on the side of the horizontally arranged pipe 51 using the second cylindrical holding part 6B of the three cylindrical holding parts 6A, 6B, and 6C of the safety light support part 3.

[0061] First, the safety light mounting support device 1 is attached and fixed to the pipe 51 in the same manner as in Embodiment 1, but in this case, when attaching and fixing the mounting and fixing part 2 to the cylindrical outer circumference of the horizontally positioned pipe 51, the second cylindrical holding part 6B of the safety light support part 3 is made to be vertical.

[0062] Next, the safety light 50 is attached to the second cylindrical holding part 6B of the safety light mounting support device 1, which is in a vertically upright position.

[0063] Specifically, referring to Figures 14 and 15(a), the body portion 53 of the safety lamp 50 is inserted from above into the second cylindrical holding portion 6B through the insertion opening formed at one end of the second cylindrical holding portion 6B, so that the protrusion 54 can be inserted into the insertion recess 7a (see Figure 12(b)). This positions the protrusion 54 in the rotation space 8 (Figure 15(b)). In this state, the body portion 52 is rotated circumferentially to position the protrusion 54 so that it can enter and lock into the positioning recess 7b. The safety lamp 50 is then dropped down by its own weight, causing the lower end surface 52a of the main body portion 52 to contact and lock with the upper end surface 6b formed at one end of the second cylindrical holding portion 6B, and the protrusion 54 to enter and lock into the positioning recess 7b, restricting rotation in the circumferential direction and positioning the safety lamp 50 in the circumferential direction (Figure 15(c)).

[0064] As a result, in this mounted and fixed state, the safety light 50 is mounted and supported on the safety light support part 3, that is, in a vertical upright position facing a predetermined direction relative to the pipe 51. Furthermore, the mounted and supported safety light 50 does not need to be tightened and fixed by the safety light support part 3; it is sufficient that the lower end surface 52a of the main body part 52 abuts and locks against the upper end surface 6b of the first cylindrical holding part 6B.

[0065] Furthermore, in the mounted and supported state of the safety light 50, the positioning recess 7b is positioned to protrude radially outward from the second cylindrical holding portion 6B beyond the portion of the cylindrical inner circumferential surface 6a corresponding to the axial direction. Therefore, the cooperative action of the protrusion 54 of the body portion 53 and the rotation space 8 of the second cylindrical holding portion 6B effectively prevents the body portion 53 of the safety light 50 from accidentally coming loose or being intentionally pulled out by illegal acts. The other configurations and functions are the same as in Embodiment 1.

[0066] Embodiment 3 This embodiment, shown in Figures 16 and 17, is similar to Embodiment 2 in that it modifies the method of use of the safety light mounting support device 1 of Embodiment 1.

[0067] In other words, in this embodiment, as shown in Figure 16, the safety light 50 is mounted and supported in a vertical upright position on the side of the vertically arranged pipe 51 using the third cylindrical holding part 6C of the three cylindrical holding parts 6A, 6B, and 6C of the safety light support part 3.

[0068] First, the safety light mounting support device 1 is attached and fixed to the pipe 51 in the same manner as in Embodiment 1. However, in this case, when attaching and fixing the mounting and fixing part 2 to the cylindrical outer circumference of the vertically positioned pipe 51, the third cylindrical holding part 6C of the safety light support part 3 is made to be vertical.

[0069] Next, the safety light 50 is attached to the third cylindrical holding portion 6C of the safety light mounting support device 1 in its vertical position.

[0070] Specifically, referring to Figures 16 and 17(a), the body portion 53 of the safety lamp 50 is inserted from above into the third cylindrical holding portion 6C through the insertion opening formed at one end of the third cylindrical holding portion 6C, so that the protrusion 54 can be inserted into the insertion recess 7a (see Figure 12(b)). This positions the protrusion 54 in the rotation space 8 (Figure 17(b)). In this state, the body portion 52 is rotated circumferentially to position the protrusion 54 so that it can enter and lock into the positioning recess 7b. The safety lamp 50 is then dropped down by its own weight, causing the lower end surface 52a of the main body portion 52 to contact and lock with the upper end surface 6b formed at one end of the third cylindrical holding portion 6C, and the protrusion 54 to enter and lock into the positioning recess 7b, restricting rotation in the circumferential direction and positioning the safety lamp 50 in the circumferential direction (Figure 17(c)).

[0071] As a result, in this mounted and fixed state, the safety light 50 is mounted and fixed to the safety light support part 3, that is, in a vertical upright position facing a predetermined direction relative to the pipe 51. Furthermore, the mounted and supported safety light 50 does not need to be tightened and fixed by the safety light support part 3; it is sufficient that the lower end surface 52a of the main body part 52 abuts and locks against the upper end surface 6b of the first cylindrical holding part 6C.

[0072] Furthermore, in the mounted and supported state of the safety light 50, the positioning recess 7b is positioned to protrude radially outward from the third cylindrical holding portion 6C beyond the portion of the cylindrical inner circumferential surface 6a corresponding to the axial direction. Therefore, the cooperative action of the protrusion 54 of the body portion 53 and the rotation space 8 of the third cylindrical holding portion 6C effectively prevents the body portion 53 of the safety light 50 from accidentally coming loose or being intentionally pulled out by illegal acts. The other configurations and functions are the same as in Embodiment 1.

[0073] Embodiment 4 This embodiment is shown in Figures 18 to 20, and uses the safety light mounting support device 1 of Embodiment 1 to mount and support the safety light 60 shown in Figure 19.

[0074] In other words, the safety light 60 is similar to the safety light 50 in Figure 11 in that, as shown in Figure 19, it consists of a main body 52 in which a light-emitting part such as an LED is provided inside a transparent container, and a cylindrical body 53 integrally provided at the lower end of the main body 52. ​​However, in addition to the protrusion 54 provided at the lower end of the body 53, a protrusion 64 is provided at the upper end of the body 53, spaced 90° circumferentially from the protrusion 54.

[0075] However, in order to vertically mount and support the safety light 60 on the upper side of the horizontally arranged pipe 51, as shown in Figure 18, using the safety light mounting support device 1, the first cylindrical holding portion 6A of the safety light support portion 3 is used, as in the first embodiment.

[0076] First, the safety light mounting support device 1 is attached and fixed to the pipe 51 in the same manner as in Embodiment 1, but in this case, the first cylindrical holding portion 6A of the safety light support portion 3 is made vertical, and the mounting and fixing portion 2 is attached and fixed to the outer circumference of the cylinder of the horizontally positioned pipe 51.

[0077] Next, the safety lamp 60 is attached to the first cylindrical holding part 6A of the safety lamp mounting support device 1 in its vertically upright position.

[0078] Specifically, referring to Figures 18 and 20(a), the body 53 of the safety lamp 60 is inserted from above into the first cylindrical holding portion 6A through the insertion-side opening formed at one end of the first cylindrical holding portion 6A, so that the protrusion 54 can be inserted into the insertion recess 7a (Figure 12(b)), and until the protrusion 54 is positioned in the rotation space 8 (Figure 20(b)). In this state, the upper protrusion 64 is positioned slightly above and separated from the upper end surface 6b of the first cylindrical holding portion 6A without contacting it.

[0079] In this state, the body portion 52 is rotated in the circumferential direction to align the protrusion 54 so that it can enter and lock into the positioning recess 7b, and the safety light 50 is then dropped in under its own weight. As a result, the upper protrusion 64 enters the insertion recess 7a, the lower end surface 52a of the main body portion 52 contacts and locks with the upper end surface 6b formed on one end of the first cylindrical holding portion 6A, and the protrusion 54 enters and locks into the positioning recess 7b, restricting rotation in the circumferential direction and positioning the safety light 50 in the circumferential direction (Figure 20(c)).

[0080] As a result, in this mounted and fixed state, the safety light 60 is mounted and supported on the safety light support part 3, that is, in a vertical upright position facing a predetermined direction relative to the pipe 51. Furthermore, the mounted and supported safety light 50 does not need to be tightened and fixed by the safety light support part 3; it is sufficient that the lower end surface 52a of the main body part 52 abuts and locks against the upper end surface 6b of the first cylindrical holding part 6A.

[0081] Furthermore, in the mounted and supported state of the safety light 60, the positioning recess 7b is positioned to protrude radially outward from the first cylindrical holding portion 6A beyond the portion of the cylindrical inner circumferential surface 6a corresponding to the axial direction. Therefore, the cooperative action of the protrusion 54 of the body portion 53 and the rotation space 8 of the first cylindrical holding portion 6A effectively prevents the body portion 53 of the safety light 60 from accidentally coming loose or being intentionally pulled out by illegal acts. The other configurations and functions are the same as in Embodiment 1.

[0082] Embodiment 5 This embodiment, shown in Figures 21 and 22, is a modification of the method of use of the safety light mounting support device 1 in Embodiment 4.

[0083] In other words, in this embodiment, as shown in Figure 21, the safety light 60 is vertically mounted and supported on the side of the horizontally arranged pipe 51 using the second cylindrical holding portion 6B of the safety light support portion 3.

[0084] First, the safety light mounting support device 1 is attached and fixed to the pipe 51 in the same manner as in Embodiment 1, but in this case, the second cylindrical holding portion 6B of the safety light support portion 3 is made vertical, and the mounting and fixing portion 2 is attached and fixed to the outer circumference of the cylinder of the horizontally positioned pipe 51.

[0085] Next, the safety light 60 is attached to the second cylindrical holding part 6B of the safety light mounting support device 1, which is in a vertically upright position.

[0086] Specifically, referring to Figures 21 and 22(a), the body 53 of the safety lamp 60 is inserted from above into the second cylindrical holding portion 6B through the insertion-side opening formed at one end of the second cylindrical holding portion 6B, so that the protrusion 54 can be inserted into the insertion recess 7a (see Figure 12(b)), until the protrusion 54 is positioned in the rotation space 8 (Figure 22(b)). In this state, the upper protrusion 64 is positioned slightly above and separated from the upper end surface 6b of the second cylindrical holding portion 6B without contacting it.

[0087] In this state, the body portion 52 is rotated in the circumferential direction to align the protrusion 54 so that it can enter and lock into the positioning recess 7a, and the safety light 60 is then dropped in under its own weight. As a result, the upper protrusion 64 enters the insertion recess 7a, the lower end surface 52a of the main body portion 52 contacts and locks with the upper end surface 6b formed on one end of the second cylindrical holding portion 6B, and the protrusion 54 enters and locks into the positioning recess 7b, restricting rotation in the circumferential direction and positioning the safety light 60 in the circumferential direction (Figure 22(c)).

[0088] As a result, in this mounted and fixed state, the safety light 60 is mounted and supported on the safety light support part 3, that is, in a vertical upright position facing a predetermined direction relative to the pipe 51. Furthermore, the mounted and supported safety light 50 does not need to be tightened and fixed by the safety light support part 3; it is sufficient that the lower end surface 52a of the main body part 52 abuts and locks against the upper end surface 6b of the first cylindrical holding part 6B.

[0089] Furthermore, in the mounted and supported state of the safety light 60, the positioning recess 7b is positioned to protrude radially outward from the second cylindrical holding portion 6B beyond the portion of the cylindrical inner circumferential surface 6a corresponding to the axial direction. Therefore, the cooperative action of the protrusion 54 of the body portion 53 and the rotation space 8 of the second cylindrical holding portion 6B effectively prevents the body portion 53 of the safety light 60 from accidentally coming loose or being intentionally pulled out by illegal acts. The other configurations and functions are the same as in Embodiment 4.

[0090] Embodiment 6 This embodiment, shown in Figures 23 and 24, is similar to Embodiment 5 in that it modifies the method of use of the safety light mounting support device 1 of Embodiment 4.

[0091] In other words, in this embodiment, as shown in Figure 23, the safety light 60 is vertically mounted and supported on the side of the vertically arranged pipe 51 using the third cylindrical holding portion 6C of the safety light support portion 3.

[0092] First, the safety light mounting support device 1 is attached and fixed to the pipe 51 in the same manner as in Embodiment 1, but in this case, the third cylindrical holding portion 6C of the safety light support portion 3 is made vertical, and the mounting and fixing portion 2 is attached and fixed to the outer circumference of the cylinder of the vertically positioned pipe 51.

[0093] Next, the safety lamp 60 is attached to the third cylindrical holding portion 6C of the safety lamp mounting support device 1 in its vertical position.

[0094] Specifically, referring to Figures 23 and 24(a), the body 53 of the safety lamp 60 is inserted from above into the third cylindrical holding portion 6C through the insertion-side opening formed at one end of the third cylindrical holding portion 6C, so that the protrusion 54 can be inserted into the insertion recess 7a (see Figure 12(b)), until the protrusion 54 is positioned in the rotation space 8 (Figure 24(b)). In this state, the upper protrusion 64 is positioned slightly above and separated from the upper end surface 6b of the third cylindrical holding portion 6C without contacting it.

[0095] In this state, the body portion 52 is rotated in the circumferential direction to align the protrusion 54 so that it can enter and lock into the positioning recess 7a, and the safety light 60 is then dropped into the rotating space 8 of the cylindrical holder by its own weight. As a result, the upper protrusion 64 enters the insertion recess 7a, the lower end surface 52a of the main body portion 52 contacts and locks with the upper end surface 6b formed on one end of the second cylindrical holder portion 6B, and the protrusion 54 enters and locks into the positioning recess 7b, restricting rotation in the circumferential direction and positioning the safety light 60 in the circumferential direction (Figure 24(c)).

[0096] As a result, in this mounted and fixed state, the safety light 60 is mounted and fixed to the safety light support part 3, that is, in a vertical upright position facing a predetermined direction relative to the pipe 51. Furthermore, the mounted and supported safety light 50 does not need to be tightened and fixed by the safety light support part 3; it is sufficient that the lower end surface 52a of the main body part 52 abuts and locks against the upper end surface 6b of the first cylindrical holding part 6C.

[0097] Furthermore, in the mounted and supported state of the safety light 60, the positioning recess 7b is positioned to protrude radially outward from the third cylindrical holding portion 6C beyond the portion of the cylindrical inner circumferential surface 6a corresponding to the axial direction. Therefore, the cooperative action of the protrusion 54 of the body portion 53 and the rotation space 8 of the third cylindrical holding portion 6C effectively prevents the body portion 53 of the safety light 60 from accidentally coming loose or being intentionally pulled out by illegal acts. The other configurations and functions are the same as in Embodiment 4.

[0098] The embodiments described above are merely preferred embodiments of the present invention, and the present invention is not limited to these embodiments; various design modifications are possible within their scope.

[0099] For example, the specific structures of the mounting and fixing part 2 and the safety light support part 3 that constitute the safety light mounting support device 1 can be modified in various ways, as long as they have the same function as the illustrated embodiment.
